I'll be curious to see your work once it's out. I've been piddling some with scripting for the girls, would like to work on setting up an easy to use template so each could have her own unique dialogue when you meet her, interact, etc.
One thing I'm debating working with is changing the way extra brothels work.
My idea is that rather than the additional brothels being new buildings in Crossroad, why not have the option to build new brothels in other fictional cities? Could group girls by tech/genre to whatever city you build the brothel in. (i.e. build one in Tokyo, pick up modern girls. Build one in Konoha, pick up Naruto girls, etc.)
